Well folks stock ISF handling isn't cutting it for me.


I am having trouble finding any solid threads with detailed specifics on any parts that are proven to increase the handling of the IS-F.

I am interested in a good shocks/springs combo that will slightly lower the car and be valved for a quick rebound without bounciness or squad/dive issues.

Usually a good set of shocks and matching linear springs take care of the body roll issue but if there is any tie bars proven to work I would appreciate if you let me know what those are.

Lots of members are going with the KW V3 coilovers. U should try typing in that in the search function to see if that maybe brings up some info on those coils.

The KW V3 coilovers are top notch. Members on here seem to love them.

BC coilovers here and love them. Also the F-Sport Rear sway bar (19mm vs stock 17mm) helps take away the stock understeer and makes the car more neutral.

I don't know what you are talking about, try using more throttle

Thank you for your response and suggestions.

You found F sport sway bar to work well in IS-F application even though is was made for the x50 models? I checked with Lexus and they said it wasnt meant for ISF and the one we have is the best to none.

Coilovers are great and all when set up correctly off course. I am looking more for a cup kit or good springs and shocks combo where the height is always constant so I don't run into extra such as corner weigh etc. I looked into Swift springs and so far like them. I wish someone gave more detailed review of the changes.

I am using all the throttle the car could offer. The car has an annoying squat that is related to the shocks mainly. Also body rolls like crazy starting at mid entry (when you shouldn't use any throttle). When you pass the apex then it settles down when you give it throttle, that's of-course if you made it pass the apex fighting excessive body roll. Not to mention the car is lazy at tun-in's to begin with.

If you are serious about increasing the cars handling capability you should start by going the coilover route and have your car corner balanced. Something you can't do with non-coilovers.

That is the under-steer that we are all complaining about when tracking the car.

Some, have tried corner balancing coilovers, F-sport rear sway bar, all of which I am planning on going with myself. Another member (SCCAForums) ran 285's on each corner to reduce the under-steer. I'm currently on 245 F, 275 R, and along with coilovers, and the sway bar I plan on picking up a set of fronts with 275's for track days.

Tried and true remedies for any car - Swaybars and/or coilovers/Springs/Shocks.

KW V3's or BC Racing coilovers are a good choice, there are equal amounts of F owners on here using those setups.

Sikky has a new adjustable rear sway bar coming out for the F in a few weeks. Setting 1 is going to be like F-Sport, 2. more aggressive 3. will be full track use. They have been testing it and the reviews are good. I will be buying it the second it comes out.

When will this sway bar be available and who makes it? Whats the price?

I think he said SIKKY - you can call them directly and verify
